    On April 26 and 27, 2023, users from the fields of laser technology, optics and laser development, as well as mechanical and plant engineering will meet in Aachen for the "7th UKP Workshop – Ultrafast Laser Technology." In addition to presenting the latest developments in ultrafast laser technology, the workshop will cover several core topics: contributions to future markets and applications from microelectronics, battery and hydrogen technology. In order to serve these topics accordingly, the UKP workshop will open its doors – for the first time – to international speakers with relevant industry knowledge to report on their experience.

    Weather reports, climate models or rocket launches – they all need precise data from the atmosphere. To acquire such data, scientists can use LIDAR (LIght Detection And Ranging) systems to shoot laser beams into the sky. The backscattered light can be used to calculate wind and temperature data at altitudes of up to 100 km. A team from the Fraunhofer Institute for Laser Technology ILT and the Leibniz Institute for Atmospheric Physics IAP has developed a portable LIDAR system that works autonomously. In the future, such systems could be mass-produced and combined into networks to provide high quality climate data.

  • IDEEL Project: Manufacture of laser-dried anodes and LFP cathodes achieved first time in a roll-to-roll process

    Press Release of the Laserline GmbH from January 18, 2023 / February 09, 2023

    Laser drying in a roll-to-roll process makes the series production of lithium-ion batteries significantly more sustainable and economical. For this purpose, a high-power diode laser with zoom optics was integrated into a film coating system in the IDEEL research project.

    The IDEEL research project aims to introduce a laser drying process as a more climate-friendly and economical method for the volume production of lithium-ion batteries. Within this context, it has now been possible to produce laser-dried anodes and LFP cathodes in a roll-to-roll process for the first time. The innovative manufacturing process significantly reduces energy consumption in electrode production and at the same time enables the drying speed to be doubled.

  • Laser systems drive the productive future

    Press Release from the Pulsar Photonics GmbH from February 1, 2023 / February 03, 2023

    Since 2021, laser processes for battery production have been researched at Fraunhofer ILT in a dedicated battery center. Here in the picture, the facility with the multi-beam optics for laser processing. In the next step, Pulsar Photonics wants to bring the optics developed for the NextGenBat project to series maturity - ideally with industrial partners.

    The EU infrastructure project NextGenBat has ambitious goals: to significantly increase the performance of mobile energy storage devices such as batteries by employing new materials and laser-based manufacturing processes. To reach these goals, the partners are using an approach that will run laser machining processes in parallel. With special optics, up to several hundred partial beams can be generated, which can then be used to significantly increase productivity through parallel processing. However, only a handful of specialist companies such as Pulsar Photonics have mastered this technology.

  • Setting off into the third dimension

    Press Release / February 02, 2023

    Fast and precise: Using the example of a molded part additively manufactured with EHLA 3D, the institute demonstrated that it could significantly reduce printing time compared to LMD and LPBF.

    Can sophisticated metal components be 3D printed productively and reproducibly in series? Researchers from Aachen can answer this question in the affirmative: At the Fraunhofer Institute for Laser Technology ILT, they have transferred two-dimensional Extreme High-speed Laser Material Deposition EHLA to a modified five-axis CNC system for the additive manufacturing of complex components. By extending the EHLA process to the third dimension, the institute can 3D print difficult-to-weld materials such as tool steels, titanium, aluminum and nickel-based alloys.

    Lasers have ignited a mini star on earth, laying the foundation for a clean energy source of the future: A historical breakthrough in inertial confinement fusion research at the National Ignition Facility at Lawrence Livermore National Lab and a defining moment for Photonics! One of the most promising applications of laser technology, the realization of laser-driven fusion, has achieved a historical breakthrough. As announced by Lawrence Livermore National Laboratory (LLNL, California, USA) in its press release dated December 13, 2022, American scientists at the National Ignition Facility (NIF) were able to release a fusion energy of 3.15 megajoules (MJ) from a pellet filled with the hydrogen isotopes deuterium and tritium. This is equivalent to 154 percent of the expended energy equivalent to 2.05 MJ of the laser pulse that triggered the explosion. This net energy gain represents the first internationally long-awaited breakthrough in fusion research. These results will provide unprecedented capability to support US Department of Energy’s High Energy Density Physics mission and established the physics platform to generate an efficient energy source comparable to the sun, making it a viable long-term complement to renewable energy.
